DETAILED DESCRIPTION OF THE INVENTION

A further description of the invention is given with accompanying drawings as follows:

Embodiment: please see FIGS. 1-9, a strap-type folding chair 100 comprises a backrest 101 and a chair seat 102, wherein the backrest 101 can be adjusted to be in a sitting state or a lying state relative to the chair seat 102 and is provided with a back side, the back side is provided with a strap 2 with an initial end and a final end, the strap penetrates through fixing belts 3 at the top of the backrest, the initial end and the final end of the strap 2 are connected to a chair frame 1 respectively, and at least one end of the strap 2 is detachably connected with the chair frame. For example, the initial end or the final end of the strap 2 is detachably connected with the chair frame 1 through a release buckle 4. The structure of the release buckle 4 is shown in FIG. 6, the release buckle 4 is provided with a male insert 41 and a female insert 42 which are connected with the strap and the fixing belt end. Two fixing belts 3 are arranged at the positions, close to the top, of the back side of the backrest 101, the strap 2 penetrates through the two fixing belts, the junction of the initial end of the strap 2 and the chair frame 1 is spaced away from the junction of the final end of the strap 2 and the chair frame 1 by a certain distance, and the distance is generally larger than the hand width so that the chair can be lifted upwards conveniently. As is shown in FIG. 3, the strap 2 is matched with the fixing belts 3 to form a double-shoulder carrying structure; as is shown in FIG. 4, the strap 2 is matched with the fixing belts 3 to form a hand carrying structure; as is shown in FIG. 5, the strap 2 is matched with the fixing belts 3 to forth a single-shoulder carrying structure.

The sitting state mentioned above refers to the backrest 101 being approximately perpendicular to the chair seat 102 in position, and the lying state refers to the backrest 101 being approximately horizontal to the chair seat 102 in position.

As is shown in FIG. 1 and FIG. 2, a buckle belt is arranged on the reverse side of the chair seat 102 and connected with an insertion base, a buckle belt is arranged on the back side of the backrest 101 and connected with an insertion head, and the insertion head 51 and the insertion base 52 are buckled together to prevent the chair from being unfolded when the folding chair is folded; the insertion base and the insertion head can also be arranged reversely, namely, the chair seat is connected with the insertion head 51 and the backrest is connected with the insertion base 52, and thus the purposes of buckling and locking can also be achieved.
